The Effect of Musicianship and Instrument Type on the Processing of Temporal Features for Speech

Due to the precision required for musical competence, musicians are more sensitive to acoustic features such as onset timing and frequency (Patel, 2011; Levitin, 2006). Musical training may enhance the processing of acoustic information for speech sounds as musicians have a more accurate temporal and tonal representation of auditory stimuli than their non-musician counterparts (Kraus & Chandrasekaran, 2010; Parbery-Clark et al., 2009; Zendel & Alain, 2008). Taken together, this suggests that musical training may enhance the processing of acoustic information for speech sounds. While our previous research did not show a musician advantage for discrimination of temporal cues (Jantzen et al., 2014; Jantzen & Scheurich, 2014) there was a trend suggesting that string musicians had enhanced performance compared to their wind musician counterparts (Davis et. al., 2015). This lack of robust results may have been due to the difficulty of the dichotic paradigm used. Therefore, the current study employed a difference-rating task using pairs of speech stimuli differing in voice onset time along a voiced to voiceless continuum. Subjects rated pairs on a scale from 1 to 7, with 1 being ‘no difference’ and 7 being ‘very different’. Musical training effects and organization of temporal features were reflected in the EEG as observed by location and amplitude of the ERP’s. In addition, behavioral results indicate that the pattern of performance on the difference-rating task varied as a function of instrument type and sensitivity to rapidly changing temporal cues that indicate a possible translation of musical cues into functional linguistic cues.
